INTERLOCKING' WALL-Brock.

To all whom it may concern:

Be it known that I, ROBERT J DYEB, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and.

useful Improvements in Interlocking Wall- Blocks, of which the following is a specification.

ments in blocks employed in the constructionof walls, partitions or other suitable structures, and has for itsprincipal objects to provide an interlocking block wherein the joint between the successive courses of the inner and outer vertical rows are broken as well as the joints between the ends .of the blocks of the same courses of the inner and outer rows, to provide a construction wherein air pasages are provided in the assembled blocks in a vertical direction from top to bottom, enabling an even temperature to be maintained for the entire hei ht of the wall and preventing the heat or cold from the exterior from readily affecting the temperature within a building having a wall of the present type, to provide a construction wherein the interior of the block is provided with suitable braces to afford maximum strength at desired points and one wherein the brace adapted to lie adjacent the joint end of the blocks of one course is of considerable thickness, thereby strengthening the wall at this point and at the same time enabling the block to be halved in a vertical direction when desired,

With the above mentioned and other objects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claim hereto appended; it being understood that various changesin the form, proportion, size and minor details of construction within the scope of the claim may be resorted to without departinfrom the spirit or fie advantages of the invention.

To more fully comprehend the invention, referenceis directed to the acompanying drawings, wherein- Figure 1 is a top plan view of a corner of a wall constructed with my improved block.

Fig. 2 is a top plan view of one of the corner forming blocks.

Fig. 3 is a vertical sectional view of the ing block earthen material burnt to a desired hardness. The present invention relates to improvev Specification of Letters Patent. P t t u 24, 1 2 Application filed August 10, 1918. Serial No, 249,284.

wall taken at its base, illustrating the break joint between the sucessive courses.

Referring more particularly to the several views of the drawings, wherein like characters of reference designate corresponding parts, the numeral 1 indicates the wall formpreferably constructed of clay or However, it isto be understood that the same may be formed of any other material, if de-- sired.

The blocks are preferably oblong in plan and are formed transversely midway of their end with a break joint brace 2 of considerable thickness, the same dividing the blocks into two parts. Each block is provided at either side of said break oint brace 2 with the intersecting braces 3 and 4;, the brace 4: extending longitudinally of the block, preferably 'midway of its width? Formed at the opposite ends of the block in line with said brace 4 is a tongue 5 and a .groove 6, the tongue being formed with a ball end and the groove being formed with a contracted throat and adapted to receive the ball end of the tongue and to provide a space 7 between the tongue and the wall of the groove for the reception of cement drawings, one of the interlocking members being dispensed with, whereby a smooth surface is provided at this poin In forming a wall composed of my improved blocks, I start the same, reference being bad to Fig. 3, with one course of blocks A of half the depth of the lowermost blocks of the rear course, whereby the joints B of successive courses of the front and rear tiers of interlocking blocks are broken, and I also arrange the blocks of the front and rear tiers so that the meeting ends of the blocks of the front tierbreak joint with the meeting ends of the blocks of the rear tier, the meeting ends of the blocks of any iven tier lying adjacent or in line with t e transverse break joint brace 2, as in the drawing, thereby providing maximum strength for the wall and insuring a circulation a1r space through the passages C for the full height of the wall.

Having thus described my invention, what I claim as new and desire to protect by Letters Patent is:--

An elongated interlockin wall block formed with one substantial y smooth unbroken face and the opposite face provided adjacent one end with a vertically disposed interlocking groove open at its opposite ends and havin a contracted throat and said face formed a j'acent its opposite end with an outwardly projecting interlocking tongue having an enlarged ead, said block being formed at opposite ends respectively with an interlocking tongue and groove each of said tongues and grooves in the face and end walls extending the full depth of the block and said tongues projecting respectively bepmili the normal side and end walls of said In testimony whereof I have signed my name to this specification in the presence of a witness.
